Tocll 'whom t may concern Be it known that I, EARL W. MANLEY, a. citizen of the United States, residing at Clint, 'in the county of El Paso and State of rTexas, have invented certain new and useful Improvements in iVheel-Bearings, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in wheel bearings and has for its pri-mary object to provide a novel device of this char- 'acter consisting of comparatively few elements whereby friction between the wheel and its axle is reduced to a minimum and the entrance of dust to the interior of the bearing obviated.

Another object of the invention resides in the provision of longitudinal bearing rollers arranged upon the wheel axle, and improved meansfor retaining the bearing rollers in position in the bore of the wheel, said wheel being provided with a lubricant con- `taining cavity opening into the bore ofthe wheel to supply the. lubricant to said bearing rollers and to the axle.

A still further object of the invention is to provide a bearing of the above character consisting of very few parts which may be easily and quickly assembled in their operativo positions, and are so constructed and arranged that the necessity of frequent repairs to the bearing will be practically eliminated.

V'Vith the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements ot the parts that l shall hereinafter fully describe and claim.

For a full underst.findingl ot the invention, reference is t-o be had to the following lcscription and accompanying drawing, in which- Figure 1 is a vertical section ot a wheel provided with my improved lnraring;4 and Fig. Q is a section taken on the line 9. 2 of Fig. 1.

Referring in detail to the drawing, 5 dce-Y ignates the wheel which in the illustrated embodiment of the invention is east in one piece and is illustrative of that type et wheel commonly used upon mine cars. This wheel is provided with a central axle receiving bore 6 which is diametrically enlarged at its ends as indicated at 7.. 'he wheel is turther provided with acentral annular chainber 8 which is adapted to contain a heavy oil or *other suitable lubricant.

9 designates the axle, the body of which is of rect-angular form, lthe end of the axle being provided with a reduced cylindrical spindle 10. Upon the spindle of the axle' the longltudinally extending-bearing rollers 11 are adapted to be arranged, said rollers contacting with the periphery lot the axlel spindle. The ends ot these rollers are reduced and rotatably mounted in the cage rings 12. These cage rings are connected by means of a plurality of longitudinal rods 13. In the bore of the wheel the bushings 1li are adapted to be fitted, said bushings be-` ing provided with keys 15 for engagement in longitudinal keyways t'ormcd in the car wheel. 'The bushings 14 at one of theircnds are provided with annular flanges 1G which extend into the enlarged ends 7 of the wheel bore 6. The inner ends of these bushings are disposed in the plane of the opposed walls of the lubricant receiving chamber 8. The outer faces of the' fianges 1G are each provided with an annular race-way 17 to receive the balls 1S. It will be noted that the flanges 16 are of less diameter than the diameter of the enlarged ends ol the bore 6 of the wheel. Between the peripherics of the flanges 16 and the annular walls of the enlargements 7 of the wheel bore, the annular washers 19 of felt or other fibrous material are disposed. These washers are of less thickness than .the thickness ot the flanges 16.

Cap plates 2O are arranged upon the axle at the outer and inner ends of the bearing and are provided at their edges with annue lar flanges Q1' tor disposition between the flanges 16 of the bushings 14 and the wall of the enlarged ends of the bore 6. rl`liese flanges engage with the packing rings or washers 19 and compress the same, thus excluding dust and dirt from the interior of the bearing and providing a secure closure at the ends thereof to prevent leakage of the lubricant. The inner faces of the cap plates Q0 are also provided with annular race-Ways 22 which are opposed to the race-ways 17 of the bushings 14 and receive the bearingballs 18. The axle spindle 10 and the outer end cap plate 20 are provided with key-ways to receive a key 9.3 whereby said cap plate is ixed upon the axle and prevented Jfrom rotating with the wheel. 5. The extremity ot the axle spindle is reduced and provided with screw threads to rece'ive a nut-24 which ei'lgagestheouter face 'of the plate 240 and kreetangularly ormedto receive the end of the body of the a'xle 9, wherebysaid inner cap plate willbe held against rotation.

In assembling the parts of the device, the inner cap plate is first arranged upon the axle. The lon itudinal bearing rollers 11 are then place in position and after the bushings 14 have been inserted ih the bore vof the wheel, said wheel is inserted over 'the axle spindle and fthelbearingrollers, it being -understoodthat thefball bearings 18 have .been properly arranged in the raceways' 22 of the cap plate.-v4 The outer series ofballs 18" are now arranged-in position and the\outer cap plate 20' arranged upon the axle, spindle and secured in position by means' of the nut 24:, so that the wheel and the bushings 14 keyed thereto may freely rotate upon the ca plates and between the series oflongtudinal rollers 11. The chamber 8 of the wheell is supplied withthe lubricant through an opening the outer end ofwhich is adapted to be closed by a threaded plug 26. A

From the foregoing` it is thought that the construction and manner of' assembling the clearly understood.

various elements of the bearing will be By means of the invention, friction will be practically eliminated and dust and dirt exeluded from the interior of the bearing. The lubricant is constantly supplied to the axle spindle in the rotation of the roller bearings 11";thus maintaining thev wheel in easy runningand serviceable condition.

AItrivill of course be apparent that while I have illustrated the invention as applied to the ordinary mine car wheel the device may `be also utilized in vehicle wheels of various :Ecrins without necessitating any material alterations in the construction or arrangem ents\of the several parts.

It will also be obvious that the invention is susceptible of considerable lmodification in the form, proportions and construct-ion of the various`parts Without departing from the essential ,features or sacrificing any of the advantages thereof.

Having thus described the invention, what is claimed is:
